EYE AND PIN FOR FLASKS.

Specification of Letters Patent.

Patented Jan. 8, 1907.

Application filed April 16,1906. Serial No. 311,961.

To all whom it may concern.-

Be it known that I, GEORGE DOWNING, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented an Improved Eye and Pin for Flasks, of whichthe following is a specification.

This invention relates to an improved eye and pin for flasks; and one ofthe objects of the invention is to secure adjustability of the eye tosecure a perfect register with the pin. 1L Another object is to providea novel pin which is detachable from the cope, so that the pins may beeasily renewed or replaced, and ins of various lengths may be applied tothe flask without rebuilding the flask.

The accompanying drawings illustrate the invention, and, referringthereto, Figure 1 is a perspective view of an ordinary straight-sideflask which is equipped With my improved eye and pin, showing one formof eye-and-pin construction. Fig. 2 is a vertical section, enlarged, online 90 90 Fig. 1. Fig. 3 is a horizontal cross-section through the eyeand pin on line 90 00 Fig. 2. Fig. 4 is a perspective view in detail ofthe eye. Fig. 5 is a plan view of a portion of the drag, showing anotherform of eye and pin, the pin being in section. Fig. 6 is a plan view ofa portion of the drag of a floor-flask, showing another method ofattaching my improved eye thereto. Fig. 7 is a perspective view, withpart klj roken away, of the form of eye shown in Referring to Figs. 1 to4, inclusive, 1 designates the drag having end pieces 2, each end piecehaving preferably cast integrally therewith a lug 3. The lug 3 isprovided with a wedgeshaped slot 4, the inclined Walls of which form aseat for the eye 5. The eye 5 is shown in detail in Fig. 4 and comprisesa wedge-shaped member, the wideend of which is provided with a V-shapednotch 6. The eyes 5 are firmly held in place in the eyeseats in the dragby forcing them in, so that they are wedged in place, and they may beadjusted to contact with the pins of the cope to secure a perfectregister of the cope with the drag. For example, if the ends of the copeand drag are out of register the eye 5 of one end of the drag may beforced farther into its seat, and the eye at the other end of the dragmay be adjusted farther out in its seat a corresponding distance byfirst removing the eye and then inserting a shim 7 on either side of it,as illustrated in Fig. 3, the eye then being again forced in tightly. Ifthe side pieces of the cope and drag are out of register, the shims onone side of the pins may be removed or reduced in thickness and theshims on the other sides of the eyes may be thickened, which will throwthe eyes toward the opposite side piece. The slot 4, as shown in Fig. 3,extends clear through the end piece 2, so that the eye may readily bedriven out from its seat when desired. Each lug 3 also has a verticalV-shaped groove 8, as shown in Figs. 1 and 2, which allows the pintoseat upon the eye. This structure of the lug 3 forms a strong supportfor the eye 5.

9 designates a pin, which in Figs. 1, 2, and 3 is shown square incross-section, but which can be modified in various ways and stillaccomplish practically the same results. instance, the pin may behexagonal, octagonal, or it may be round in cross-section, as shown inFig. 5.

The end pieces of the cope 10 are provided with lugs 11, formingpin-holders, each pinholder having a vertical hole, which may be cutsquare, as shown in Figs. 1, 2, and 3, or which may be cut round orhexagonal or otherwise, and the pins 9 project through the pin-supports11, and each pin is secured detachably in place by means of awedgeshaped key 12, which is inserted in the horizontal slot 13, formedin the pin-holder 11. Thus by removing the keys 12 the pins 9 may beremoved from the pin-holders and other pins of different lengthssubstituted, if desired. It is obviously an easy matter to adjust thepins 9 vertically, if desired.

The keys 12 are made of sufiicient length so that they may be utilizedas handles for lifting the cope.

In the form shown in Fig. 5 the eye 5 is mounted in an eye-holder 14,the eye-holder 14 being secured to the drag 1 by screws 15. Theeye-holder 14 is provided with a wedgeshap'ed slot similar to the slot 4of the preceding form, and the eye-ho1der 14 has a horizontal slot 16,into which the small end of the eye 5 protrudes, which affords a chanceto insert an implement to force the eye 5 from its seat when desired. Inthis form the eye-holder 14 has a semicircular concave groove whichallows the passage of the round pin 9 shown, and the eye 5 is also For -instead of the V-shaped notch.

provided with a concave semicircular notch (Shown in Fig. 4.

Figs. 6 and 7 show another form, in which the eye 5 has pins 17 casttherein, forming means for attaching the eye direct to the drag of awooden floor-flask.

This device is especially designed and adapted for iron flasks, althoughI do not limit myself to its use with iron flasks solely, as it may alsobe applied to wooden flasks.

What I claim is 1. In a flask, an eye comprising a wedgeshaped memberhaving a notch, the drag of the flask having a wedge-shaped slot forreceiving the eye. 2. In a flask, an eye comprising a wedgeshaped memberhaving a notch, the drag of the flask having means for receiving theeye,

20 the cope of the flask having a pin-holder provided with a pinhole, apin mounted in the hole, and means for detachably holdingthe pin in thehole.

3. In a flask, eyes comprising wedgeshaped members each having a notch,the drag of the flask having wedge-shaped slots in eachend piece, thecope having pln-holders on each end piece, each pin-holder having apin-hole, pins in the holes in the pin-holders, each'pin-holder having atransverse slot and keys in the transverse slots in the pinholders fordetachably holding the pins in
